CVE-2026-62850
FreeScout: Administrative tools.php endpoint is accessible to low-privileged users, enabling filesystem enumeration and unthrottled brute-force of application secrets
FreeScout is a self-hosted help desk and shared mailbox. Prior to 1.8.225, the administrative tools.php maintenance endpoint is reachable without an appropriate authentication or access-control boundary. Response differences for attacker-controlled path values disclose whether arbitrary directories and files exist on the server. The same endpoint validates application-key and database-password candidates without rate limiting, per-session throttling, or a CAPTCHA, allowing unrestricted guessing attempts against application secrets. This issue is fixed in version 1.8.225.
